Summary: This study demonstrates that the absorption and reflection edges of SrV1-xMoxO3 solid solution can be shifted to the edges of the visible light spectrum, making it a potential alternative to indium tin oxide (ITO) with extremely low sheet resistance. The optimum composition with x = 0.5 shows a resistivity of 32 mu omega cm and transmittance above 84% across the visible spectrum. The shift of the plasma frequency is governed by the interplay of d-band filling and electronic correlations. This research contributes to the understanding of highly conducting perovskites for sustainable transparent conductors and emergent plasmonics.

Summary: This work proposes a novel transparent conducting electrode (TCE) based on electrostatically doped graphene monolayers to overcome the limitations of indium-based TCEs in perovskite/silicon tandem cells. The electrode utilizes a thin film dielectric charged and interfaced to a graphene film, allowing for modulation of charge carriers in graphene through electrostatic doping. Experimental results demonstrate that short-duration dielectric charging can significantly reduce the sheet resistance of graphene without impacting the transmission of light. The deposition of negative electrostatic charge enables precise tuning of charge concentration from n-type to p-type.

Summary: The electronic and magnetic properties of (LaCrO3)(m)/SrCrO3 superlattices are investigated using first principles calculations. It is found that the magnetization in the superlattices is dependent on the value of m, due to charge ordering with different oxidation states of Cr ions. The transparent p-type semiconductors with finite magnetization can be used to fabricate transparent magnetic diodes and transistors with potential technological applications.

Summary: Electrochromic (EC) batteries have great potential in applications such as smart windows and wearable electronics. However, the lack of stable electrolyte and matching EC electrodes remains a challenge for achieving high working voltage window and energy density. In this study, a highly transparent ion-conducting film (ICF) was used to develop a rechargeable EC battery. The ICF exhibited high optical transparency and ionic conductivity. An electrochromic battery (ICF-ECB) was fabricated using the ICF, with Li4Ti5O12 (LTO) and LiMn2O4 (LMO) as the EC layer and counter electrode, respectively. The ICF-ECB showed high energy storage performance, cycling stability, and a reversible color transition between discharge and charged states, providing real-time information on the energy level and work status of the device.

Summary: The universality of 2D multiferroics in the Ca-based double-perovskite bilayer system has been demonstrated, showing that the breaking of inversion symmetry correlation between initial and final polarization states is crucial for achieving the transition of magnetization. Only the switching of tilt distortion can cause a change in the direction of magnetization, making multistep switching of tilt distortion via ferroelectric switching the lowest energy barrier pathway for controlling magnetization by an electric field.

Summary: The intensity of Raman bands on substrates with transparent overlayers can be enhanced by optical interference, leading to incorrect interpretation of Raman signals. This study proposes a model to determine the enhancement factor based on the reflectance response of the whole structure, even when the thickness and refractive index of the overlayer are unknown. Experimental evidence supports the model's validity, aiming to establish a correlation between reflectance and Raman spectroscopy.

Summary: The effect of thickness on the magnetic property of amorphous carbon thin film is investigated. It is found that the thickness variation affects the microstructure and chemical characteristics of the films, leading to changes in their magnetic properties. The presence of weak ferromagnetic coupling between unpaired spins at sp2 sites is observed, and the saturation magnetization of the film decreases with increasing thickness.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
